I notice that the Conti GP 5000 I have and even the old GP II 4's, have a direction of rotation on the sidewall. Now mind you I so far have put the tires with the proper rotational direction, but what happens if you don't. My guess is if you put them on the opposite way then does the bike go backwards when I start pedaling? Do the tires wear out different, or possible be off balance. But seriously what is the catch?
